Description

Another array/constructor problem...

The following, looks like it should create a new Runner instance with String[]...

<snip>
class Runner implements Runnable
{
String[] args

Runner(String[] args)

{ this.args = args }

void run()

{ println("hi") }

}

String[] args = new String[]

{ "a", "b" }

println(args)
println(args.class)
runner = new Runner(args)
</snip>

Running with groovy outputs:
